Technical Requirements and Design

 

Purpose

 

The purpose of this deliverable is to define and document technical requirements for the project and its eventual rollout, and to create an initial technical design. The technical requirements define all technical areas of the project and where they integrate with business requirements, including any expected service level agreements. Included in this deliverable is the integration of the new solution with existing solutions and their future operation.

 

How should it be produced

 

·         Define the system landscape, describing all relevant technical systems in diagrammatic and textual form.

·         Define the client deployment strategy, detailing the SAP clients to be utilized and configured, and the technical settings for each client in each system.

·         Define the transport strategy, defining the plan for moving SAP change requests through the system landscape.

·         Produce a technical questionnaire or use the Quicksizer Project tool, to determine hardware sizing based on business and technical requirements.

·         Prepare the hardware order, to procure all physical hardware necessary to fulfill the solution landscape requirements, and all remote connections to SAP.

·         Define all technical standards and procedures that itemize development and configuration methodologies to be employed throughout the project’s lifecycle.

·         Define all security concepts, describing how the solution will be secured at all levels, from network and database to users and authorizations.

·         Define support strategy, which are a documented plan, organization and its procedures used to define the support of the production solution.

 

What if it is not done

 

This is a key deliverable.  The implementation cannot proceed without defining and documenting all aspects of technical design.  Technical scope, timeline or budget cannot be controlled if they are not clearly defined and serious problems can impact negatively on the project.

Additional Information

 

It is critical to have a clear analysis of the current solution landscape prior to defining any e technical requirements. A careful examination of the existing infrastructure, the business processes it supports and integration details to the SAP solution is necessary to complete the technical requirements.
